CAC Wackett Drawings
The aircraft:
As World War II loomed on the horizon, the Royal Australian Air Force was seeking an aircraft suitable for training the new generation of pilots who would soon be needed to defend the country or fight with the allied forces in Europe. So the R.A.A.F. issued Specification 3/38 for an intermediate trainer and the Wackett Trainer was developed to meet this need.
The first two CA-2 prototypes were initially powered by in-line 4-cylinder Gypsy Major II engines, but these turned out to be underpowered. They were then modified to be powered by more powerful 6-cylinder Gypsy Six engines, however these were not produced locally and were not available from the UK. The final solution was found in the US-produced Warner Super Scarab 7-cylinder radial engine. In this new form, the CA-6 Wackett met the requirements of the RAAF trainer specification, and 200 Wacketts were constructed and saw service with the RAAF and the Dutch East Indies Air Force (now Indonesia).
